ABSTRACT

An intelligent towing plug apparatus and software system that performs trailer electrical system testing, diagnostic and monitoring routines as well as towing vehicle plug testing utilizing wireless technology housed completely inside a towing adapter plug or attached towing plug compartment housing that interfaces with any smart phone or towing vehicle on-board computer system that has downloaded or preinstalled the intelligent towing plug mobile application or software compatible with the on-board computer&#39;s operating system.

BACKGROUND

For both consumer and commercial trailer use a safety check is required to ensure that the trailer systems, lights, brakes, etc., are working properly before the trailer is pulled onto a road and into traffic. Trailer and truck plug wiring is often exposed to harsh elements, road dirt and debris that can cause damage to the wires and failure of the electrical circuit needed to operate a particular trailer electrical system. The testing of the trailer system typically requires two people—one to manually engage the circuits from within the towing vehicle such as turning on the lights, turn signals or pressing the brake pedal, and one person to stand behind the trailer and observe whether the circuits are visibly working such as brake lights illuminating. Often when a circuit is found to be not working it takes considerable time, effort and expertise to determine if the problem is with the trailer system or the truck plug. There currently are products in the marketplace that can be attached to an idle trailer's plug and using an external battery source (not the towing vehicle) test the circuits of the trailer to determine any faults within the system. However, these test units are large, heavy and require a 12 volt battery or connection to a 110-120 volt electric power receptacle to provide the power needed to test the trailer system's circuits. Many of these systems also do not provide any diagnostic tools within the system nor are they capable of testing the towing vehicle's plug. These type of testing units are predominately used by truck/trailer rental yards. There are also products in the marketplace that can be installed onto the trailer body itself and then are wired to the trailer wire harness that is connected to the trailer plug. These type of units use the towing vehicle's 12 volt power supply to test the trailer systems. These systems can be wired or wireless such as U.S. Pat. No. 6,525,654 and they require that a separate display device be installed within the cab of the towing vehicle such as a truck/tractor so that the results of the testing and monitoring system can be viewed by the driver. These systems require installation and expertise by the user to correctly and properly wire the transmitter unit to the trailer wiring harness and install the receiver display unit inside the towing vehicle. This level of installation expertise is far beyond the knowledge and skills of the average towing vehicle user or owner. These type of systems are not portable or mobile to be easily and quickly installed and used with multiple towing vehicles and trailers. They also are not capable of testing the towing vehicle's trailer towing plug. It would be highly desirable to have a device that can test a system circuit on both the trailer and struck side of a plug. It would also be highly desirable to be able to monitor those systems in real time while the trailer is being towed so that any fault of any of the electrical circuits within the trailer system could be immediately known and safety precautions taken to ensure the safety of the passengers in the tow vehicle as well as those on the road in the vicinity of the trailer. There are no industry standards for this type of trailer system monitoring from within the towing vehicle nor are there systems provided by truck/tractor manufacturers as standard equipment to provide this type of trailer safety monitoring feature and functionality. There is a need for a simple, universal, inexpensive and highly portable and mobile testing and monitoring system that can be quickly plugged into industry standard plug types without any expertise and easily monitored with a highly available off-the-shelf hand held display unit that can easily fit in your pocket or be displayed in the cab of a towing vehicle. A highly desirable unit would be quickly and easily plugged and unplugged from one towing vehicle or trailer to another and automatically test the trailer systems and vehicle towing plug before using the trailer, diagnose any broken circuits or faults and then monitor the trailer systems in real time while the trailer is in use. An ideal ‘plug and play’ device would be compatible with industry standard 7-pin, 7-blade, 6-way round, 4-way round, 5-way flat and 4-way flat wiring adapter plugs without any customization of any kind making the product highly useful for both the consumer and commercial user. A highly desirable version of a device would also be compatible with the NATO military 12-pin plug.

There is a plurality of uses for a mobile battery powered embodiment of the present invention consisting of an intelligent towing plug and mobile app.

The power source for this exemplary embodiment of the present invention could also be a 110-120 v electrical outlet source utilizing a power adapter.

FIG. 6 shows an exemplary high level view of the circuit power management of a 7-pin or 7-blade plug in the test & diagnostic mode of the intelligent towing plug when the trailer is parked and idle and the monitor mode when the trailer is in use.

FIG. 6 is an exemplary high level power management chart of two of the functional routine modes of the preferred embodiment of the intelligent trailer plug in a commercial 7-pin or consumer 7-blade industry standard plug configuration when it is plugged into the towing vehicle's trailer towing plug and the trailer adapter plug. The mobile app initiates these mode sequence routines through the user interface of the intelligent towing plug mobile app or software version compatible with a computer's operating system which controls the intelligent towing plug's PCB components through the wireless module as described in FIG. 1 and FIG. 4 or a hard-wired communications BUS to the towing vehicle's on-board computer system as described in FIG. 4. Other routine modes include but are not limited to battery mode and towing vehicle plug test mode.

1) Trailer Test & Diagnostic Mode—Continuous power to all circuits but the brake circuit. In this example, the brake can only be tested when the brake pedal of the towing vehicle is engaged for safety reasons. (Insures the system does not automatically put the brake on while the vehicle is moving.) This test mode sequence can run in continuous serial mode testing each circuit one at a time or static mode testing all the circuits at the same time. The test mode cannot be run while the towing vehicle and trailer are moving unless the user indicates through a series of prompts in the mobile app user interface that the towing vehicle and trailer are stationary as shown in FIG. 7. This reduces the risk that the trailer lights are turned on and off during the test sequence routines while the trailer is moving and thereby creating a safety hazard for other driver's of other vehicles in the vicinity of the moving tow vehicle and trailer. Only in battery mode can the brake circuit be automatically tested when a trailer is not hooked up to a towing vehicle.

2) Trailer Monitor Mode—Power is provided to each circuit only when the driver of the towing vehicle engages the circuit, i.e. uses the turn signal, turns on the lights, pushes the brake pedal, etc. Whenever there is a broken circuit or fault, the PCB will send a signal to the mobile app or vehicle on-board computer system giving both a visual light indicator as to where the problem is as well as sound an audible alarm.

The mobile app or software version compatible with a computer's operating system can initiate a plurality of routines including a towing vehicle towing trailer plug test to display each circuit signal from the towing vehicle and indicate whether the signal is being received by the towing vehicle plug or not as well as internal plug electronic diagnostics to the trailer systems for locating over currents (short circuits) and low currents (open circuits) as examples only.

The default state of the plug is in trailer monitor mode. When the trailer test mode function is engaged the system is automatically reset back to monitor mode when the test is complete and the results are displayed on the screen of the smart phone or towing vehicle on-board computer monitor screen so that the vehicle lights do not come on while the vehicle is in motion which could be a safety hazard (turn signal or brake lights displaying while moving). This default monitor mode will also automatically turn off the continuous power mode (if this routine is engaged) to the trailer system after the test is complete so the towing vehicle's battery doesn't run down because the lights are continuously on when the trailer is not in use and the vehicle engine/alternator is not running to keep the vehicle's battery charged.

While in trailer monitor mode the system can be put into trailer test mode but only after the user acknowledges a series of warnings for safety reasons as illustrated in FIG. 7. And even then the brake circuit can only be engaged by pressing the brake pedal so that the system cannot automatically engage the brake while the towing vehicle and trailer are moving. Only in battery mode can the intelligent towing plug automatically test trailer brake circuits and systems.

FIG. 7 shows an exemplary high level functional flow chart showing an intelligent towing plug trailer test routine initiated from a smart phone mobile software application or towing vehicle on-board computer system using intelligent towing plug software.

FIG. 7 shows an exemplary flow chart of the trailer test mode routine initiated by the intelligent towing plug mobile app or software version compatible with a computer's operating system for the intelligent towing plug utilizing the intelligent towing plug PCB as described in FIG. 1. The default state of the intelligent towing plug is monitor mode as described in FIG. 6.

The user initiates the trailer test sequence routine by selecting the test button 200 on the mobile app. or software version compatible with a computer's operating system. A second screen 201 displays and queries the user as to the towing vehicle and trailer's state. By indicating the towing vehicle is stopped and in park then the system will begin the test sequence routine. If the user indicates the towing vehicle and trailer are not stopped then the test is not run and the routine ends.

If the test sequence routine is selected, a display warning 202 followed by a second query 203 requires the user to again confirm the towing vehicle and trailer are not moving. This step in the routine reduces the risk that the trailer lights are turned on and off during the test sequence routines while the trailer is moving and thereby creating a false light indicator and safety hazard for other driver's of other vehicles in the vicinity of the moving tow vehicle and trailer. If the user indicates that the tow vehicle and trailer are not stopped then the test cannot be run and ends. If the user answers YES then the test sequence begins by asking the user to select the standard plug type 204. Plug type 204 are examples only. In another version of the intelligent towing plug software or mobile app the intelligent towing plug will automatically identify the plug type by circuit and pin configuration so plug adapters can be easily used with the intelligent towing plug.

The test sequence routine is then started in continuous serial mode testing each circuit one at a time or static mode testing all the circuits at the same time (routine option button not shown). The results of the test 205 are displayed on the mobile app or on-board computer user interface. If circuit faults are displayed then the user will receive a separate diagnostic user interface and routine.

The next set of routines is the brake test initiated by the user through the user interface of the mobile app with a query 206 asking the user if they want to test the brakes. If the user indicates NO, the test sequence ends. If the user indicates YES, then the brake test routine begins by instructing the user to push the brake pedal 207. The brake circuit is tested and the results are displayed 208 on the user interface of the mobile app. After the test is complete the system is set back to monitor mode 209.

At any time during the test mode the user can stop the test sequence routine by selecting STOP TEST 210 which is always displayed on the mobile app user interface during testing mode routines.

This high level flow chart of the trailer test sequence routine of the intelligent towing plug is an example only of the sequences and routines initiated from the mobile app or software version compatible with a computer's operating system and performed by the PCB inside the intelligent towing plug or attached compartment housing as described in previous figures and embodiments of the present invention including FIG. 1. There is a plurality of variations and sub routines to the various modes of the preferred embodiment of the present invention including but not limited to trailer test and diagnostic mode, trailer monitor mode, battery mode and towing vehicle plug test mode as examples.
